Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, especially a kind of auxiliary tool device of operation for the treatment of prostate and similarly need insert man-made support, specifically a kind of rifle cribbing inserter.
Background technology
At present, support is inserted in utilization in prostate and similar human body organ method treatment commonly encountered diseases is a kind of effective method for treatment, and it has, and operation is little, patient is painful little, and surgery cost is low, alternative excision is particularly useful for inoperable gerontal patient.
For support is inserted in the patient body, people have invented various storing apparatuses, disclose two kinds of storing apparatuses as Chinese patent ZL962036536 and ZL992590906, and they all need not the cystoscopic auxiliary storing that can realize prostate bracket.Operate inconvenience but they all exist, during operation, the doctor needs to hold apparatus with one, and another pulls moving associative operation parts, will rock because of uneven generation of exerting oneself in the operation like this, increases misery to patient, even patient is caused damage.
Summary of the invention
The purpose of this utility model is at the unhandy problem of existing support inserter, designs the rifle cribbing inserter that hands of a kind of need can be finished whole operations.
The technical solution of the utility model is:
A kind of rifle cribbing inserter, comprise outer tube 7, interior pipe 8, handle 11, gun stock 12,13, gun stock 12,13 is symmetrically arranged, it is characterized in that outer tube 7 is fixed on the top of handle 11, binding site place at gun stock 12,13 is installed with setscrew nut 3, one end of interior pipe 8 links to each other with setscrew nut 3, is provided with the draw-in groove that handle 11 is moved therein between gun stock 12,13; Handle 11 inserts in the gun stock 12,13, and back-moving spring 14 is installed between them; Support 9 is installed between outer tube 7 and the interior pipe 8, on the interior pipe 8 of mounting bracket 9 front ends inclined-plane bayonet 10 is installed, and the microcephaly of inclined-plane bayonet 10 is towards the direction of handle 11.
Described setscrew nut 3 is installed between the gun stock 12,13, is fixed with bolt 1 on it.
The utlity model has following advantage:
1, easy to operate, operative doctor can as pull the pistol trigger utilize one hand operate can will place outer tube be placed on the human body corresponding site.
2, simple in structure, installation, easy to use.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the local structure for amplifying sketch map of bayonet position among Fig. 1.
The specific embodiment
Following structure drawings and Examples are further described this utility model.
As shown in Figure 1, 2.
A kind of rifle cribbing inserter as device for posting prostate bracket, comprises pipe 8, handle 11, gun stock 12,13 in outer tube 7, the rustless steel, and gun stock 12,13 left sides are symmetrical part, the gun stock of being convenient to grasping that the two is as a whole altogether, as shown in Figure 1.Outer tube 7 is fixed on the top of handle 11, at gun stock 12,13 binding site place is installed with setscrew nut 3, one end of interior pipe 8 is mutually bonding with setscrew nut 3, at gun stock 12, be provided with the draw-in groove (not shown) that handle 11 is moved therein between 13, between setscrew nut 3 and interior pipe 8, sealing ring 4 is installed also, handle 11 inserts gun stock 12, between 13, be provided with location thimble 15 between them, be set with back-moving spring 14 on the thimble 15 of location, support 9 is installed between outer tube 7 and the interior pipe 8, on the interior pipe 8 of mounting bracket 9 front ends, inclined-plane bayonet 10 is installed, and the microcephaly of inclined-plane bayonet 10 is towards the direction of handle 11, as Fig. 2.
In order to use observation facilities in doctor's operation process, on gun stock 12,13, guide pad 2 is installed also.
Setscrew nut 3 is positioned on the handle 12,13 by the draw-in groove of self and the draw-in groove of handle 12,13, and bolt 1 links to each other with setscrew nut 3.The function of bolt 1 is to make things convenient for the doctor to insert the tubing equipment; Setscrew nut 3 and interior pipe 8 are bonding, thus the fixed-site of pipe in making.
During use, hold gun stock 12,13, pull handle 11 backward, handle 11 moves under the constraint of the draw-in groove between the gun stock 12,13 backward, driving outer tube 7 simultaneously moves backward, bayonet 10 is fixing with support 9, thereby makes the part support discharge outer tube 7, release handle 11, spring 14 resets handle 11, outer tube 7 drives support 9 reaches (inclined-plane of bayonet 10 is to the not constraint of reach of support 9, and some is released support 9, and the front port of outer tube 7 has constraint to support 9).Pulling handle 11 repeatedly can take off support 9 easily and place in the patient body from interior pipe 8.Compression handles 11 is during to range, and the big face position of bayonet 10 is just to the mouth of pipe of outer tube 7.
